Combining magnetism and light to fight cancer

Combining magnetism and light to fight cancer

By combining, in a liposome1, magnetic nanoparticles and photosensitizers that are simultaneously and remotely activated by external physical stimuli (a magnetic field and light), scientists at the Laboratoire Matière et Systèmes Complexes (CNRS/Université Paris Diderot) and the Laboratoire Physicochimie des Electrolytes et Nanosystèmes Interfaciaux (CNRS/UPMC),2 obtained total tumor regression in mice. Non-toxic when they are not activated, such therapies can also achieve a reduction in adverse effects. These results, which demonstrate the importance of multiple treatments, were published in ACS Nano on 24 March 2015.
